Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In a commonly used Multi-RAT system, a wireless network based on IEEE 802.11 (i.e., Wi-Fi technology) has a characteristic of high throughput but poor stability, while a Long Term Evolution (LTE) wireless communication technology is a wireless communication technology applied to a cellular mobile communication network, and although the throughput is low, it is very stable and the packet loss rate is low. The Multi-RAT system is formed by combining two links of Wi-Fi and LTE, and is used for analyzing a control plane of the Multi-RAT system, so that the Multi-RAT system for assisting the determination of the access point of the client is provided for solving the problem that the access point of the client is not the optimal access point of the wireless access link when the client selects the access point of the Wi-Fi in the system, and the details are as follows.
Fig. 1 is a schematic structural diagram of a multiple radio access system according to an embodiment of the present invention, which is described in detail as follows.
In the embodiment of the present invention, the multiple wireless access systems include a client 110, a server 120, an LTE base station 130, and multiple WIFI access points 140 (multiple access points are not shown in the figure, and only one access point is taken as an example), where the client 110 is connected to the server 120 through the LTE base station 130, that is, a second wireless access link, and the client 110 further selects one of the multiple WIFI access points 140 and connects to the server 120, that is, a first wireless access link.
In this embodiment of the present invention, the client 110 is configured to obtain access information of a plurality of access points of a first wireless access link, and send the access information to a server through a second wireless access link, where the access information includes signal strength and identification information. The client 110 is further configured to determine the optimal first radio access link access point according to the identification information after receiving the identification information of the optimal first radio access link access point returned by the server 120.
In this embodiment of the present invention, the server 120 is configured to determine, after receiving the access information of the multiple first radio access link access points, an optimal first radio access link access point according to a preset access point auxiliary selection rule and the access information, and return the identification information of the optimal first radio access link access point to the client 110 through a second radio access link.
In the embodiment of the invention, in a Multi-RAT system of an industrial internet of things, a client is generally an industrial internet of things device, in fact, a low-power industrial personal computer connected with an embedded industrial internet of things device through an ethernet is generally used as the client, specifically, the low-power industrial personal computer is provided with a WIFI and LTE communication module, and is deployed with a Multi-RAT system client. In addition, the functions of the embedded industrial IoT equipment can also be directly put on an industrial personal computer, so that the special embedded industrial IoT equipment with the closed protocol can also use the Multi-RAT system. At this time, when client software of the Multi-RAT system is run on the industrial personal computer, the industrial personal computer executes the functions of the client and is respectively connected to the LTE micro base station 130 and the Wi-Fi access point 140 through the LTE link and the Wi-Fi link.
In the embodiment of the present invention, a wireless Access Point, that is, a wireless Access Point, is generally abbreviated as AP, and for convenience of description, the AP will be referred to as a first wireless Access Point, that is, a Wi-Fi Access Point.
In the embodiment of the present invention, the identification information usually selects the local area network address of the AP, that is, the mac address, but may also be other unique identification information of the AP.
In the embodiment of the present invention, after determining the optimal AP, the client 110 usually connects to the optimal AP using an iwconnect command, but of course, the core of the present invention lies in the process of determining the optimal AP through the assistance of the server, and in fact, after receiving the optimal AP information returned by the server, the client determines to access or perform other steps, which is not limited in the present invention.
In the embodiment of the present invention, the client 110 may obtain the access information of the AP by executing an iwist scanning command, the implementation process described above belongs to a conventional technical means well known to those skilled in the art, and the present invention is not described in detail herein. Considering that the Wi-Fi driver of the client has limited functions and may not support the acquisition of the negotiated rate, the negotiated rate needs to be acquired from the AP, at this time, the sshpass tool may be used to execute a command on the AP and obtain a result, and the iw station dump command may be used to acquire information of all clients, including the negotiated rate, and redirect the output of the sshpass tool to a file and then read the content of the file.
In the embodiment of the present invention, to facilitate understanding how to determine the optimal AP of the client in the Multi-RAT system provided by the present invention, as shown in fig. 2, an interaction flow between the client and the server in the Multi-RAT system is specifically provided, and specifically, reference may be made to a timing diagram of the Multi-RAT system shown in fig. 2 and an explanation thereof.
As a preferred embodiment of the present invention, the specific steps of the server 120 determining the optimal AP can refer to the contents and explanations of fig. 3 to 6.
In the multiple wireless access systems provided by the embodiments of the present invention, when a client needs to select to access a first wireless access link access point, access information including signal strength and identification information of multiple first wireless access link access points is first obtained, then the access information is sent to a server through a second wireless access link, and a server uniformly determines an optimal first wireless access link access point to which each client should connect according to the received access information of access points sent by multiple clients and a preset access point auxiliary selection rule, and then returns the identification information of the optimal first wireless access link access point to the client so that the client determines the optimal first wireless access link access point to connect. Compared with the conventional technical scheme that the client actively selects the wireless access link access point, the multiple wireless access systems provided by the embodiment of the invention can respectively determine the optimal wireless access link access point of each client under the condition of collecting global information by using the server to assist in determining the wireless access link access point of the client, thereby avoiding that a large number of clients simultaneously access to the same wireless access link access point and improving the network performance of the multiple wireless access systems.
Fig. 2 is a timing diagram of various wireless access systems according to an embodiment of the present invention, which is described in detail below.
In the embodiment of the invention, after the client triggers and selects the optimal AP, access information of a plurality of first wireless access link access points, that is, access information of WIFI access points, including the strength and identification information of each WIFI access point, is acquired, wherein the identification information is information representing the unique identity of the WIFI access point, and the mac address of the WIFI access point is usually selected. The access information of the WIFI access point acquired by the client may be acquired through an iwist scanning command, and a specific implementation manner belongs to a conventional technical means that can be adopted by technical personnel of the present invention, and is not described herein again.
In the embodiment of the invention, the influence of a complex environment in the industrial internet of things is considered, the network performance of the WIFI access point is constantly changed, and it can be understood that the optimal AP triggered and selected by the client is not only initially added into the Multi-RAT system, but also can be periodically triggered and selected according to a preset rule, namely the AP selected and accessed by the client is periodically adjusted, so that the Multi-RAT system is always in a better network operation state.
In the embodiment of the invention, after the client collects the access information of the WIFI access point, the information is sent to the server through the second wireless access link, namely the LTE wireless access link, the server receives the access information of each WIFI access point and can respectively determine the optimal WIFI access point of each client by combining with the global information, and the WIFI access point is independently selected relative to the client, so that the technical problem that the communication performance of the client is influenced because the selected WIFI access point is not good or a large number of clients access to the same WIFI access point due to the fact that the WIFI access point is overloaded when the clients access to the same WIFI access point is unavailable can be effectively solved.
In the embodiment of the invention, after determining the optimal WIFI access point of each client, the server sends the identification information of the optimal WIFI access point to the client, so that the client can determine the optimal WIFI access point according to the identification information and is connected to the optimal WIFI access point through an iw connect command.
As shown in fig. 3, a flowchart of a step for determining an optimal access point for a server according to an embodiment of the present invention specifically includes the following steps:
step S302, determining the first wireless access link access point corresponding to the received access information as a feasible access point.
In the embodiment of the present invention, all WIFI access points obtained by scanning by the client are determined as feasible access points, and in fact, in consideration of a complex environment of the industrial internet of things, in an actual application process, many other WIFI access points that do not belong to the Multi-RAT system may be scanned by the client, at this time, information of the WIFI access points needs to be screened, the WIFI access points that do not belong to the Multi-RAT system should be deleted, at this time, the access information should also include a service set identifier of the WIFI access point so as to facilitate screening of the WIFI access points by the service end, and specifically, refer to fig. 4 and an explanation thereof.
Step S304, determining the feasible access point with the highest signal strength as the candidate access point.
In the embodiment of the invention, after the feasible access points are determined, the feasible access point with the highest signal strength is preferentially determined as the candidate access point, so that the signal strength of the WIFI access point accessed by the client is ensured.
Step S306, determine whether the number of current access clients of the candidate access point exceeds a preset threshold of the number of access points. When judging that the number of the current access clients of the candidate access points exceeds a preset access point number threshold value, executing a step S308; when it is determined that the number of currently accessed clients of the candidate access point does not exceed the preset threshold value of the number of access points, step S310 is executed.
In the embodiment of the invention, the number of the clients which are accessed by each WIFI access point is represented by setting parameters, the maximum allowable access point number threshold of the WIFI access point is set, whether the number of the clients currently accessed by the candidate access points exceeds the preset access point number threshold is judged, if the number of the clients which are accessed by the WIFI access points exceeds the maximum allowable access point number threshold, a large number of clients are accessed to the same WIFI access point, the network performance of the clients under the WIFI access point is influenced due to overlarge load of the WIFI access point, and at this time, the optimal WIFI access point of the client needs to be determined again.
In the embodiment of the present invention, the preset access point number thresholds of the WIFI access points are generally set to be the same, but may also be related to the actual performance of the WIFI access points.
Step S308, deleting the candidate access point from the feasible access points. And then returns to the step S304.
In the embodiment of the invention, the WIFI access points with the number of the accessed clients exceeding the maximum allowable access point number threshold are deleted from the feasible access points, namely, the WIFI access point with the highest signal strength is determined as the candidate access point again from the rest access points, and then whether the load of the WIFI access point exceeds the limit is judged again.
Step S310, the candidate access point is determined as the optimal first wireless access link access point.
In the embodiment of the invention, the candidate access point has the best signal strength among the access points of which the number of the currently accessed clients meets the preset condition, namely the number of the currently accessed clients does not exceed a certain threshold, so that the candidate access point can be determined as the optimal first wireless access link access point, and the problem of load imbalance and overall performance reduction of the system caused by connection of a large number of clients to the same WIFI access point due to active decision of the clients is solved through the process of determining the optimal access point by the server.
As shown in fig. 4, a flowchart of a step of determining an optimal access point for a server according to another embodiment of the present invention is provided, which is described in detail below.
In the embodiment of the present invention, the difference from the flowchart of the step of determining the optimal access point by the server shown in fig. 3 is that the access information further includes a service set identifier; the step S302 specifically includes:
step S402, determining the first wireless access link access point belonging to the multiple wireless access systems according to the service set identifier, and determining the first wireless access link access point as a feasible access point.
In the embodiment of the invention, in an actual application environment, other WIFI access points which do not belong to a Multi-RAT system usually exist, and a client cannot judge whether a certain Wi-Fi access point belongs to the Multi-RAT system, so that a service set identifier of the Wi-Fi access point, namely an SSID, needs to be acquired, and then the acquired SSID is sent to a server, and the server determines the Wi-Fi access point which belongs to the Multi-RAT system and is a feasible access point according to the SSID, so that the client cannot be connected to the WIFI access point which does not belong to the Multi-RAT system.
Fig. 5 is a flowchart illustrating steps for determining an optimal ap for a server according to another embodiment of the present invention, which is described in detail below.
In the embodiment of the present invention, the difference from the flowchart of the step of determining the optimal access point by the server shown in fig. 3 is that, after step S310, the method further includes:
step S502, updating the number of the access clients of the optimal first wireless access link access point.
In the embodiment of the present invention, since the determination of the optimal WIFI access point of the client belongs to a continuous process, when the client sends a request and changes the optimal WIFI access point of the client, the number of access clients of the WIFI access point needs to be updated, and the data is used for comparison with the threshold of the number of access points in the subsequent step S306 to determine whether the number of connection clients of the WIFI access point exceeds the limit, so as to determine whether the WIFI access point can be determined as the optimal WIFI access point of another client.
Fig. 6 is a flowchart illustrating steps for determining an optimal ap for a server according to still another embodiment of the present invention, which is described in detail below.
In the embodiment of the present invention, the difference from the flowchart of the step of determining the optimal access point by the server shown in fig. 3 is that, after step S310, the method further includes:
step S602, determining whether the client is connected with a first radio access link access point in advance. When the client is judged to be connected with the first wireless access link access point in advance, executing step S604; and executing other steps when the client is judged not to be connected with the first wireless access link access point in advance.
Step S604, updating the number of access clients of the first radio access link access point.
In the embodiment of the present invention, similarly, it is considered that the determination of the optimal WIFI access point of the client belongs to a continuous process, and therefore when the client is connected with the WIFI access point in advance and the optimal WIFI access point is determined again through the server, the number of access clients of the previously connected WIFI access point needs to be updated in addition to the number of access clients of the optimal WIFI access point.
